BARREL.

SPECIFICATION forming part of Letters Patent No. 718,020, dated January 6, 1903.

Application filed March 12, 1902. Serial No. 97,813. (No model.)

To all whom it may concern:

Be it known that I, ELwooD O. PHILLIPS, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metallic Barrels and the Like, of which the following is a specification.

The present invention relates to a fluidtight barrel or other like package formed of two or more sections which are stamped, drawn, or spun from sheets or blanks of metal and united together at their meeting edges to form a fluid-tight barrel or package; and the present improvement has for its object to provide a simple and efficient formation and construction of a sheet-metal barrel or package embodying the features of great lightness, combined with strength and simplicity of construction combinedwith economy of manufacture, all as will hereinafter more fully appear and be more particularly pointedout in the claims.

In the accompanying drawings, illustrative of the present invention, Figure 1 is a central longitudinal section showing a completed sheet-metal barrel made in accordance with the present invention from a central and two counterpart end sections welded together by electric or other like welds to constitute a single integral structure; Fig. 2, an enlarged fragmentary section taken at line a: as, Fig. 1, with a view to illustrate the arrangement of the bung-hole bushing and which also illustrates a modified form of the present improvement, in which the central and one end section are primarily formed as a single part and subsequently attached to the other end section by an electric or other weld to constitute a single integral structure.

Similar numerals of reference indicate like parts in both views.

Referring to the drawings, 1 and 2 are substantially counterpart sections formed from a sheet or blank of metal by any of the usual spinning, stamping, or drawing operations common in the art of sheet-metal working, and while it is preferable to make each of said sections of a single integral piece of metal the scope of this part of my present invention embraces the formation of said sections from two or more pieces of the required size and shape welded together by the electric or other suitable welding process. Each of said sections 1 and 2 is of a cylindrical form and will usually be of a flaring form to afford the usual belly or bilge to the completed barrel.

3 and 4: are the ends or heads, which will usually be formed integral with the main sections 1 and 2 and insetted, as shown, to form the annular chimes of the completed barrel.

5 is a central member or section of an annular or ring shape and which in the present invention is formed of sheet metal in any usual manner and with a crowned or dished main portion and a narrow cylindrical extension 6 at one or both sides.- Such extensions 6 are of a diameter corresponding with that of the ends of the sections 1 and 2 and are adapted to be joined thereto by the electric or other suitable welding process.

In some cases thecentral member 5 may initially constitute an integral part of one of the main end sections aforesaid and, asillustrated in Fig. 2 of the drawings, without departing from the spirit of my present invention. Preference, however, is given to the initial formation of the same as a separate piece and its subsequent union with the sections 1 and 2 in that the manufacture can be carried on in a more economical manner and with greater rapidity and simplicity in the operations.

The material feature of the present invention lies in the provision of the narrow cylin drical extension 6 at one or both sides of the dished central section 5 in that with such required in forming the butt-welds between the respective sections as the same are forced together while in a heated condition in the operation of welding, and with a view to have a smooth exterior at the welds, with the weld enlargements formed wholly within the interior of the barrel, as shown in the drawings, an outer die will surround the exterior of the barrel, as usual in the operation of Welding tubular metal bodies by the electric welding processes now in general use.

7 is the bung-hole bushing, formed of duetile metal and expanded in place in any usual manner in a hole formed therefor in the crowned portion of the central section 5.

It is evident that in the manufacture of barrels and the like embodying the present invention the sections 1 and 2 may be made of parts or pieces of the proper shape and secured together to form the described sections instead of being formed integrally from a single piece of metal in accordance with the judgment of the constructor and the particular size or use for which the package is intended, and while I prefer the plain form of shell shown in the drawings the same may be corrugated longitudinally or circumferentially, if so desired, without departing from the spirit of my invention.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. A wrought-metal barrel or the like composed of sections welded together and having a central bilge portion, concavo-convex in longitudinal section, suitably connected at one end to one end section and at the other end provided with a cylindrical extension adapted for attachment by welding to the other end section, substantially as set forth.

2. A wrought-metal barrel or the like composed of sections welded together and having a central bilge portion, concavo-convex in longitudinal section and provided with cylindrical extensions at its respective ends adapted for attachment by welding to the respective end sections, substantially as set forth.

Signed at Chicago, Illinois, this 5th day of March, 1902.

ELWOOD O. PHILLIPS.
